the problem is that when i open these property page, after the values are initializated, the apply command is enable. can anyone tell me why?
PS: these hapens without the user change the values.
thanks

using these line:

changed=true

is the only way for enable the apply command, right?

after recived the values, i simply put these line:

changed=false

thanks to everyone
