Hi,

I'm running ME8 on Win XP SP3.

My Problems are abrupt crashes to desktop when closing or opening editors (not alway, 3 times today)

gbrinkmann,
Can you give some more information?
1. Can you copy paste your installation details from MyEclipse > Installation Summary > Installation Details?
2. What is the type of editor that you are working on?
3. Can you switch to to a new workspace and check if the issue persists?

Editors I'm working with are standard Java Editor, MyEclipse JSP Editor, Colorer XML Editor and Properties Editor.

It's my third ME8 workspace, the problems also occurred in the other workspaces.

gbrinkmann,
Thank you for the details? Can you try using -clean as given in the following link -
http://myeclipseide.com/PNphpBB2-viewtopic-t-10280.html.

Also, can you narrow down to any file in particular that is causing the issue and send us that file? You can send a mail to support@myeclipseide.com and attach your file. Please add ATTN:Shalini in the subject and refer to this post. This will help us replicate the issue internally.

hello again,

3 weeks later: i think i can narrow down to one or both of two editors: colorer xml editor and/or colorer jsp editor.

the problem seems to be resolved since i use myeclipse editors instead of the above mentioned, no crashes to desktop anymore.

i cant narrow down to specific files. maybe this helps: our xml and jsp files are quite large sometimes, filled with heavy property and EL usage.
also our jsp files may not always be well-formed, since we disabled ide validation in the past because of performance problems.

cheers
g.

Good to know that you are all set.
The crashes could be caused due to compatibility issues with the base eclipse.
Do let us know if you have any issues
