--- Comment #23 from Eliot Blennerhassett ewblen+wine@gmail.com 2010-06-29 23:45:31 --- Just to clarify, as it is maybe not obvious from the descriptions unless you use OrCad.
Orcad has a main drawing window. When "Place Part" is activated, a dialog box appears allowing selection of the part to be placed. Then click OK, the dialog closes, the focus returns to the main window, with the part to be placed attached to the cursor. Clicking the mouse then places the part into the schematic.
Even with Comment#3 patch, if the cursor is moved outside the Orcad window, and back in, the windows repaints and the part is no longer attached to the cursor. So as #3 suggests, the problem is something to do with loss of focus of the main window.
