My 9.5.6 x64 sometimes freezes

My Opus Directory 9.5.6 x64 sometimes freezes when I click on a file or a program file in it.

Of course it's a strange behaviour, 'cause 32bit version does not show this problem.

Is there something I could do to resolve it?

Thanks

It's not a 32-bit vs 64-bit issue. (Lots of people use the 64-bit version fine and you can't have installed the 32-bit version on the same machine you tried the 64-bit version on. It's likely to be something on the 64-bit machine that is conflicting.)

The information in these FAQs should help track down what is causing the freeze:

[ul][li]Crash, exit or high CPU usage when viewing certain directories[/li]

[li]General slowdown or instability investigation steps[/li][/ul]

Maybe I was right: I uninstalled 9.5.6 and installed 9.5.5 and got no problem since 2011.02.13...

Try installing 9.5.6 again; I bet the problem doesn't come back, but if it does that might help locate what's going wrong on your machine.
