Crashes and Bugs found ..

Wonder if anyone else is running into this or not.. 
 I had a few crashes now where sonar just freezes When I use the smart tool's Select feature on automation nodes. It freezes up before i can delete the selected nodes.. It dose not happen all the time but It has happened about 5 times on different tracks and in a different project. Also the envelope I was selecting was  Volume..

 Second problem I been finding ,is I'm running out of memory while auditioning loops from the browser , A restart fixes it for a while then it rums out. .. I would assume a memory leak .. But the only plugins Im using are from NI komplete 7 and a few included with Sonar. Nothing that have not been using for years. . So it seems something else might be happing .. Then again after auditioning a loop why would it be saving the memory in the ram. Shouldn't it clear it.. dunno just askin..  
 
 And another issue that I have run into ,  is groove clipping , on a certain project I cloud not save with out gettin failed to save document or out of memory when I was able to save I noticed it took a long time for the process to happen lets save almost 10 seconds or longer sometimes. So I preceded to bounce all groove clips , and a quick save after each bounce, What I noticed was the saving process was getting quicker, when I had bounced all groove clips down to clips, the save process was almost instant.. At that point I opened a few other projects that had alot of content and took a long time to load up ,and I preceded to bounce those groove clips down to clips... and now saving is almost instant..  I just did a test I took a .wav loop grooved clipped and copied it on 14 tracks and stretched them out about 100 bars and clicked save it took time for the save process , now I took the same loop and copied it onto 14 tracks again and copy pasted it the same length as I did with the groove clips, and the save process Now was almost instant. Another thing I notice is the white screen before loading is gone too with no groove clips in it .. 

Can any one else confirm this test.. Is it normal that a groove clips takes up this much more memory? 
I will send in a report as soon as Im sure its something that should not happen .. A quick fix was to fix this problem but has not... Thanks for your Help John.
