slown down of IDE 2.9 under windows

[Malte Brill]

Hi Tiemo,

I have seen this once. The reason was that the messagewatcher did not  
reset the messageMessages to false after closing. So you might want to  
test in the messagebox:

put the messageMessages

If it is true then set the messageMessages to false and see if that is  
any help.

Best,

Malte
