[PD-dev] annoying crackles--Gui issue

i have been using pd-39 from the cvs this week and for some reason i am experiencing click and crackles when the gui refreshes. when i delete or move an object, i get a harsh crackle through my sound card. this is even more present when i load a sound file into an array. i don't get this if i use the official 40. not sure if i should be posting this here or not but just wondering if it is a issue for anyone else?

also, what are developers working on the most at the moment. 38-dev 39-dev, 40, desire etc. what would be the most useful to be testing and what has the best functionality, opinions?. all but desire seem to have the annoying paranoid closing question whenever i want to close a patch. even unedited help files etc.

thanks
