Trying out effects leads to crashes of X1d Studio

I'm a fairly new user of X1d (but have used ProAudio9 and SHS7 for years) and have been trying out effects, mainly reverb, to see what they do.  I start with a simple project with a 3-4 midi tracks routed to TTS-1 routed to a busA routed to the main output.  I put an effect into the effects bin of busA and then try various presets.  Then I'll delete the effect and try another one.  After doing this a few times X1d will invariably crash.  Since I'm just testing nothing is lost but under different circumstances something could be lost by the crash.  I'm using only plugins distributed along with X1d.

Is this just to be expected?  I don't recall SHS7 doing that.  And it was just about impossible to ever get PA9 to crash.

Curiously,

The FXs are Cakewalk Studioverb2 and Sonitus:fx Reverb.
I believe it has happened every time (at least 3 or 4 times) I have done a lot of testing of the reverb presets.  I don't know how long it takes since I haven't really done controlled testing.

By crash I mean I get the windows box that says something like "Sonar has experienced an error and will now exit - want to send info to Microsoft?".  I don't send info.  After dismissing the Windows error message Sonar says something about a proper shutdown hasn't happened and do I want Sonar to try and save stuff.  I don't since I'm just testing.   Then Sonar is gone.

Here's some entries from the Windows Event Log:

Faulting application sonarstd.exe, version 18.0.5.534, faulting module sonarstd.exe, version 18.0.5.534, fault address 0x0031c28f.

I am not up on my Intel specs but does the Intel Core 2 Duo E7500 meet the minimum specs for X1? The SONAR X1 spec sheet recommends a minimum of an Intel Core 2 Duo E8200. Could this be a case of pushing the hardware too much?

edit: reformatted to see if FF 15 works properly....it doesn't

that's an odd one, then, Larry. 

the only other thing that I can think of would be the versions of those plugins.  are you using the latest version of those plugins or are you using the versions that came with HS7?

I retrieved the Shared Plugs folder from a time before X1d was installed and checked the versions of the two reverbs I was testing with.  Both have older versions.  So all I can say is that the versions were updated when X1d was installed.
