OPUS locking up after over a year's use

Hello - I've been using Opus for quite a few years. I currently have 11. I am running Win7. I have not changed hardware or installed new drives, etc. But now Opus after a short time of use will lock up. I reinstalled and it was fine for about a week, but is now doing it again. Rebooting corrects it temporarily, so it must be holding onto memory, but I don't know how to correct this. I used the dual vertical layout with a viewer pane. thanks - Suz

One or more of these guides may help, depending on exactly when the problem occurs:

[li]Crash, exit or high CPU usage when right-clicking certain files[/li]
[li]Crash dumps for bug reports (if it is crashing, not just freezing)[/li]
[li]General slowdown or instability investigation steps (if none of the others seem relevant)[/li][/ul]
