--- Comment #3 from Paul Romanyszyn pgr@arcelectronicsinc.com 2009-06-20 09:56:57 --- I have obtained eagle v3.55r3 from cadsoft and can confirm it fails as described. Ubuntu 9.04 does not like compiling older then wine-1.0 rc3 or wine 3499cb96b69d Fixing that compile problem only works to about wine-0.9.60. Testing with wine-1.1.24 I can swap using the task bar but get the error whenever the mouse over pop up hint is activated on any of the tool bar icons. I can supply traces and the application demo should be able to be obtained via private mail.
