Re: FolderBrowserDialog hangs the application

Some additional info... this is the second time I'm posting about this
issue... the first time I tried rebooting and it seemed to work. This time
it works once after the reboot, then fails again.

I used the SysInternals process explorer to try and get some add'l info.
After the application hangs, processexplorer says that there is still 1
thread running. The info it gave was 0x7c810867 followed by
NTdll.dll!RtlConvertUiListToApiList+0x276 for the thread. When I hit the
"module" button in process explorer it caused a "Properties window" (like
when you right click a directory and hit properties) to pop up against one
of my directories! Now that is weird.

I'm in no way an windows xp internals expert but I was hoping that this
might make some sense to somebody out there.

I'm at a loss here. I can't imagine that my PC configuration is so very
different that I'm seeing a problem that nobody else is seeing.

If anybody has any ideas, I would greatly appreciate them.

Thanks, John
