SolidWorks hangs up, when removing Component-filter

Hello,

when I use this "X", SolidWorks hangs up. 

It does this only, while my plugin is running. But there isn't any Code executing in the plugin.

When I remove the filter by clicking in the textbox und typing backspace, everthing is okay.

When I stop my plugin before clicking on "X" and reconnect again after, everthing is okay.

Can I find a crash-log anywhere?

You can I find out, why SolidWorks hangs up?

Thankfull for any help,

Samuel
