I just installed EmEditor on a Windows 7 beta (64 bit) machine. I noticed that the the drop target line that appears when dragging text stops moving shortly after I start to drag a selection of text. I would guess this issue is probably specific to Windows 7, but I thought I would post the issue in case it affects 64 bit Vista as well or if it can easily be fixed :)
I couldn’t reproduce your issue even though I am using the 32-bit Windows 7 beta in a Virtual PC. The gray vertical rectangular caret still appears and moves when I am trying to drag and drop text.
