Hello,
With the latest NeoOffice Release, I frequently get 100% CPU usage while doing strictly nothing (except having a 152 pages document opened). As someone else experienced this problem?
Please note that I really don't know if this is with the latest version or it started a few patches ago, but I am quite sure I don't remember having the fan spinning like hell because of an opened document.
Regards.

The next time that this happens, can you take a sample of the NeoOffice application using the Activity Monitor application and attach the sample? From such a sample, I can usually see where in the NeoOffice code (or its underlying OpenOffice.org code) the high CPU usage is occurring.
Instructions for using the Activity Monitor application are available in this NeoWiki article.

Hi patrick
Here is the sample of NeoOffice.
Regards.
Your sample indicates that NeoOffice is spending all of the sample time executing some Java-based grammar checking code.
Since no Java-based grammar checking code is shipped with NeoOffice, I suspect that you have installed a third party extension that is performing grammar checking of your entire 100+ page document.
If you select the Tools :: Extension Manager menu, are there any extensions listed that appear to do grammar checking? If so, can you disable those extensions, quit and relaunch NeoOffice, and see if the 100% CPU usage reoccurs?
If the 100% CPU usage reoccurs while your grammar checking extensions are disabled, please collect a new Activity Monitor sample and attach it and I will compare it to your first sample.

Hi Patrick
You are absolutely right. The culprit is Language Tool!
Once I deactivated it, CPU usage reverts back to something normal.
I still do not understand why "suddently" I got this behavior.
Maybe some corrupted settings somewhere.
Anyway, thanks for your support and sorry to have mobilized some of your resource for nothing.

I would suspect that document length is what Language Tool is sensitive to. I would assume that grammar checking a 150 page document takes roughly 150 times longer than checking a single page document.
