I have a problem with an old but still very useful plugin "My Streams". I need it to watch some on-line .asf video streams. As I understood this plugin is using Windows Media Player to play the stream and it was running fine on MP 1.0.2.
After upgrading to 1.1.0 RC1 I have the following problems:
- pressing "space" does not pause the video
- pressing left or right arrows which should act as Rewind/FF - causes MP to crash. Actually it seems to keep running in the background but I see the Windows desktop.
- if the stream not found - there is a message about that and after pressing OK - I see a black screen.

I assume that similar problems may happen also with the other plugins which are using WMP.
Please find a log file attached.
Thanks for a help!
