Slow response scenario with version 6.0.1

One of our programmers is having slow response issues in version 6.0.1. This 
started happening recently. He basically has the same machine as the rest of us 
in the shop (2gb mem, 3.4ghz cpu, etc.)

1) He is having sporadic cursor movements like in previous versions.

2) He positions to a line, right-clicks>Select>Select line, drags the cursor 
for about 20 lines to highlight code, crtl-f to perform a search, with Restrict 
search to selection checked, he enters a find a nd replace value and finally 
selects Replace all. His PC comes to a halt with javaw.exe at 90+ cpu. It will 
complete however. It takes a couple minutes though.

I can duplicate his same actions and do not have an issue. We were both working 
with SQLRPGLE source.

Now, if he goes to Window>Preferences>Remote Systems>iSeries>LPEX Editor 
Parsers>ILE RPG and deselects Automatic syntax checking his performance issue 
goes away. Select it again and the pissue returns. My machine has it selected 
and I have no problems.

Any ideas?
