FULL PRODUCT VERSION :
1.4.2_12

ADDITIONAL OS VERSION INFORMATION :
Windows XP service pack 2

A DESCRIPTION OF THE PROBLEM :
Our apps, which uses a COM integration library crashes after opening the ActiveX control after about 20 seconds.

This worked fine under 1.4.2_10.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Difficult, as it is very involved, and it relies on Java2COM software from NevaObject (which I think also supplies the ActiveX bridge).
