When I start pd it seems to be fine, but then it shows a message saying that pure data closed unexpectedly, ignore and restart, if I click restart it never start, what can I do to solve that? thanks.

I need some help! suddenly in some patches number boxes, sliders, output objects etc, the values are not displayed or are frozen. when I minimize the window and then maximize, the numbers and sliders update the value but again I can't see it when I change it, I don`t know why is happening if someone knows please let me know!! it will be useful for me now. I'm using a pc thanks, best regards.

I had 10.7.3 but yesterday I update the OS to 10.7.4 and now is working perfectly. I think that knowing the reason could be useful anyways, because maybe in other moment it could happen again, thanks.

Further, when I save the patch in another folder,the trouble seems to be fixed, but then just happen again.
