So I just finished reformatting my Windows 7 x64 machine because Pd, for some unknown reason, had spontaneously stopped working on it.

On my newly repaved machine, I just re-downloaded Pd-extended 0.43.4 and installed it to find that I can't seem to move objects, message boxes etc around with the mouse (yes, I am in edit mode).

I can select objects with the mouse, and then move them around the canvas with the arrow keys, but not with the mouse. The mouse works fine toggling toggles, banging bangs etc, and otherwise my patches seem to work fine.

Am I missing something obvious or is this a bug with Windows 7. Has anyone else had this problem?

(I tried uninstalling and reinstalling, but the problem persisted. also I tried installing 42.5, and mouse seemed to be okay - although it didn't find any of the libraries)

Any ideas or suggestions would be greatly appreciated.

I had the same thing today on win xp. In the pd window, Edit>preferences>reset to default in the pd search path seems to solve the problem, don't know why though. Hope it works for you too.

I'm having this exact same issue on Windows 8. Restoring to defaults didn't fix the issue. Anyone have any other recommendations?

This happens to me from time to time... What I think is happening is that there is another instance of Pd hung in the background. Exit Pd, make sure it's really gone in task manager, & I think you'll be ok...

I had this problem, and turning on my sound card made the mouse start responding. I not even kidding!

I have experienced this problem and I've found that is related to the audio device selcted in pure data being used by another application, in fact if I disable all the audio devices in pure data or if I choose another audio device everything works
