I'm using Tri 6.4.1 on XP pro on this Dell precision M90 laptop.
This is more of a reporting of a percieved bug than a cry for help since I have a workaround. The workaround is never open the text editor to full screen mode and all is well.
Just to summarize, and I have tried this in both version 1.4.2_06 and 1.4.2_19 JRE, scrolling the text window of the function editor while it is in full screen mode causes "javaw.exe" resource usage to go through the roof per task managers "Processes" monitoring tab on my machine. Also there is an accompanying condition of a painfully slow und seemingly unpredictable scrolling of the text window while this is going on. Once this mode has been entered I haven't found a way back out other than closing out then restarting my tri session.
If I were to guess I'd say it looks like it may be some issue with the directx graphics handling but of course it is only a wild a** guess. It looks to me like all graphics acceeration is disabled in this combination of conditions.
Then again I've seen errors with this machine you all couldn't seem to replicate so maybe this is another flaw of this particular laptop.
