i'm having an ongoing problem where archicad 'stops responding'; it's not crashing, and the error reporting function doesn't come up - it just hangs. Typically it will occur when i change applications (to check email, use web browser, work on a document etc.) and then when i try to return, archicad doesn't come back (application tag still visible, but windows task manager gives status as not responding). Usually also, using 'end task' in the windows task manager won't work (i get the pop-up asking me to confirm i want to end the task and then, after i confirm, the pop-up asking if i want to send a report, which i've done) but the application remains open but not responding.
Sometimes, i can terminate the archicad application using 'end process' however this is not always successful and i need to restart my computer to reset it.
I'ts typically happening with one project (over several revisions with different file names) however as its the project i've been working on recently about 80% of the time, i can't be sure it's an issue with the file or statistically more likely to happen while working on this file.
A similar thing was happening previously when rendering or rebuilding large models, however i assumed that was due to lack of resources - since upgrading RAM, CPU usage is usually less than 10% when application stops responding.
I'm not sure where to start in diagnosing this; any suggestions would be appreciated.
