Thanks for the reply. Running WinXP SP2, ATI Radeon Xpress 1150, driver ver 8.30.0.0. I have two systems connected through a multi-monitor KVM switch, but this box is single monitor only, the other one is but not the one with the problem. The enter key works sometimes, but more often not. I haven't figured out why it does sometimes & sometimes not... yet.
This issue only occurs if there's any window that covers the IB window. I haven't tried it partially covered yet and will get back to you.
