If I move a python module in the PyDev Package Explorer using drag and drop from one package to another, the target packages shows the dragged file twice until I restart eclipse. I assume that is a bug?
This happens using Eclipse 3.3.2 with PyDev 1.3.18 on Ubuntu 8.04
Seems like a bug... I tried it in a simple test here and haven't been able to reproduce it, so, please report that as a bug giving information on how's your project configured / pythonpath folders and as much info as you can so that I can properly reproduce it.
