Sonar X3 Producer - can't edit piano roll, or use browser

Hi, I've just started with Sonar X3 Producer, coming from FL Studio, but I can't work out what I'm doing wrong. The Browser completely ignores any mouse clicks, it won't respond, but the rest of the program responds, and also the PRV doesn't work either - am I supposed to be using a specific tool from the top left hand corner to edit/use these windows? I've tried all of them, I thought maybe I had to turn on some sort of 'edit' mode or something, to start working?
I can open the Tutorial Projects, such as SONAR_AudioDemo, and play it back, but I can't work out how to edit the piano roll, or even choose a VST from the browser. I can insert a VST using the drop down menu Insert, Soft Synth, VST2, but when I open the piano roll I can't do anything with it - can't close it, nothing in the piano roll window responds to the mouse (but all the rest of the program does, so it hasn't frozen).
Edit: I just opened the tutorial 'Snap and Smart Grid Producer' and I can now click on the Browser while that is open, and add a VST instrument, change the Edit Filter to 'Notes', then I was able to draw on a piano roll under the audio in the playlist (?) with a magnifying glass view. If I then Alt-3 to view the piano roll, I can see the separate piano roll, with the notes I entered in the 'magnified' piano roll, but I can't do anything with it, it doesn't respond to the mouse.
I can open and close both the Browser and the Dock by pressing 'B' or 'D', but when I click on any part of them, nothing responds, can't close them by clicking on the 'x', can't select anything, can't access the menus.
 
What am I doing wrong? Sorry for being a newbie.

Hi, many thanks for your help. I tried all of that and got the piano roll maximised, but it just won't respond. Initially there was a caret displaying in it, instead of the mouse pointer, for about ten seconds (Smart Tool was active), but either way, nothing I do in it works, it just ignores all mouse clicks, like the whole of the dock is frozen, it doesn't matter what I open in the dock part, they are always frozen, whereas the rest of Sonar works. Very strange. I will try a reinstall.

Possibly. I think the best thing you can do is contact Cakewalk Support - what you are experiencing isn't "normal" and I can't recall hearing of anything similar.
 
What OS are you running?
 
It might help to put your computer specs in your signature while you are experiencing problems, just saves lots of questions from forum users.

+1 FastBikerBoy This is too weird something major is going on. Give Cake a call.

call support...

How are you trying to enter notes into the prv?
 
A simple click with the mouse doesn't do it - there are 3 different ways to achieve this:

1. Use alt + enter
2. Double Click
3. Click & Drag

i can confirm this issue, but my config is slightly different I am sure.
 
First, my X3 install on my studio PC is rock solid, no issues at all.
 
However, I just got done installing Sonar on a new MacBook Pro retina.  I used Boot Camp and installed Windows 7 Home Premium, the same thing as I run on my studio PC.
 
I am seeing the same behavior.  I can show and hide the browser using B but the mouse does nothing.  Curiously, the mouse work on everything else without a hitch, including Pro Channel.  To me, this rules out a mouse driver issue.
 
in addition, I cannot get the PRV to show no matter what I do.  Hot key doesn't work and neither does selecting it from the menu.  This is a fresh install and I have applied X3d.
UPDATE: The PRV does show now.  That was pilot error.  It shows in the multidock but is minimized by default.  The only issue I am now having is the browser.  I simply can't figure out how to get it to function.  Clicking with the mouse just simply isn't working.I have tried a USB mouse along with the trackpad of the MBP.  Same results...nothing,
 
I am using a Saffire 2i2 interface and a Axiom Pro 49 keyboard.  I have 8 GB of RAM and a 256 GB SSD (standard for the rMBP) along with an attached G Drive via USB. I have not installed any other VSTs at this point.
 
Very strange behavior indeed.  I will monitor the thread and also let you know if I fid a solution.
 
UPDATE: This issue only seems to happen to me if I am starting with a blank project.  If I start with a template, the browser is available and works as expected.  Not sure why the blank project is an issue and it certainly doesn't occur on my studio workstation, but I can easily work around it.  Hopefully this will help the OP.
