Thanks for report about cs 1.5, will fix it.
Bomb defusing isn't working as expected as well as buttons usage, to be done in near future
Radius 0 problem, looks like a bug, will do some research.
Known bugs so far:
1. The above things
2. Bots something became dumb with switching weapons primary<->secondary, when both weapons are empty.

cs 1.5 support to be revised, it's seems it's completely broken now...
