Well, I can`t think of a better reason. It is also possible that opening
media files while CPU is overloaded with other tasks like audio/video
compression causes the problem. That`s why I wanted to prevent Explorer from
opening multimedia files. I`ve set all folders` view to 'Details', so
explorer will open all multimedia files to display dimentions and duration.
This is usefull with audio-files, but consumes a lot of resources so I want
it disabled for video-files.
Tracking the exact source of a problem that will not occure every time is
not easy and takes a long time. I`d like to try if it will occure with video
preview disabled. But how do I disable it? I know that I have to erase a
handler for the AVI file type from the registry - something that points to a
CLSID key, but I don't know witch exactly. I play with regedit frequently
and I always have a fresh backup :-)

Hello George,
Thanks for your response.
Do you mean the issue only occurs when you use audio-video editing tools
or
codecs?

| The problem will only occure some rare times, and I assosiate it with
| audio-video edditing tools or codecs. The last time only SoundForge and
| VirtualDubMod was running. MPEG2 codecs are the ATI build of Cyberlink.
and
| AVI codec (for both video and audio) is ffdshow. It's most likely that
| explorer and ffdshow don't like each other, so I'd like to disable
thumbnail
| preview and any other code that is trying to open AVI files in explorer,
| when I select or drag them. I guess that explorer will not dispose and
clean
| the memory of AX controls after using them and this causes my problems.
| Sooner or later, a thread may stuck infinite looping and eating memory.
