Can not see my plug in window ????

[Tibo2004]

Hi,

I recently started experiencing a weird behavior with plug ins (Battery, FM8...).

When I load the VST or AU it loads properly and I can change the preset from Live but i can not see the actual plugin window ??? It does that sometimes, it's very strange. I click on the the "tool" icon in Live but nothing shows up. The plugin works fine, it's just not showing the window... usually by restarting Live everything works properly.

Thank you for your help.
