Problems jumping to java 6

I have an applicattion under java 5 and it works just fine

but when i installed the ver 6 the actionPerformed of the

JComboBox works strange and do some weird things

like do nothing or dont displays the things

or take a lot of time to do it correctly

Someone can tell if this is a bug or in the ver 6 is

another event who do the same as the actionPerformed in ver 5

TKS
