I need a bit more information to fix this problem - the text of the currently edited file and/or the messages.log to see whether there were some exceptions logged.

I am marking this report as incomplete - after someone adds just tiny bit of more info please reopen and we will deal with it.

The suspected problematic method is
org.netbeans.modules.editor.url.Parser.recognizeURLs

I am looking at it right now ...
Comment 5 David Strupl 2010-10-12 07:36:45 UTC 
Vladimir, can you please send me the file which was visible in the editor when this happened? It would help me a lot to be able to reproduce it ..  Thanks in advance.
Comment 6 David Strupl 2010-10-12 09:43:09 UTC 
Jan promised to have a look at his code to check what might be wrong. My last comment with the request that we would like to have the file in question still holds.
Comment 7 Vladimir Voskresensky 2010-10-12 10:31:21 UTC 
David I will upload file as soon as would have access to it.

Unfortunately slowness does not reproduced on standalone file.
You should download ACE+TAO sources, build ACE+TAO, create C/C++ project and open file "reopened_modulesS.cpp" from created project.
