FabFilter

When using Fabfilter C2 in Reaper ( docked ) a preset load forces the whole main reaper window to switch from fullscreen to a user sized window. Also the graphics of C2 behave unconsistently, sometimes when activated they fill the whole fx docker window,
sometimes they look normal sized. Other fabfilter plugins (C2,L,MB) seem to work well.

sorry, typo :
fabfilter Q2,L,MB seem to work well.

This happens because Pro-C 2 can resize its interface depending on whether the Side Chain section is enabled. Reaper doesn't cope very well with this unfortunately -- it works, but sometimes the FX window gets bigger than it needs to be and Reaper doesn't make it smaller again.

Cheers,
