ok just did a quick test using windbg from the above link (fwiw, there are multiple exceptions just starting up sonar (not quite latest version btw))
so, if you can repro an issue every time, and aren't scared by swathes of programmer gibberish, you can try this to identify the culprit:
install windbg from above link
before starting sonar, run windbg - but don't do anything with it yet
start sonar (so the sonar.exe process has started) and switch back to windbg
in windbg, go to the file menu and select "attach to process" then select sonar.exe from the list
switch back to sonar and do stuff - if an exception is encountered, sonar will freeze and windbg will flash in the task bar
switch back to wndbg and see what it's highlighting - usually something benign, but might be something so make a note
switch back to sonar and continue doing stuff
repeat above steps 5-7 until you hit your particular issue, give this info (and possibly the whole windbg output) to the support@cakewalk folks
if your issue is a crash-to-desktop-without-warning-or-crash-dump, this should also catch that
you can also use windbg to read any dump file created, and to analyse other apps causing trouble
