Kaillera crashes CCS64 V3.0 Beta 1.3

[Heckenpenner]

Every time I open up a Multiplayer game in CCS3 by pressing F3, and the Kaillera client pops up, the CCS emulator itself freezes. The graphics are no longer updated (you can "wash them away" by dragging the Kaillera window over the CCS window), and the CCS window doesn't show any reaction anymore - until I close the Kaillera client. Then everything is fine with CCS again. I tried Kaillera 0.89 and 0.9, I deactivated visual styles in XP (read it somewhere concerning MAME), but nothing did work for me. Who can help out?
