There seems to be a change in the behavour in file sync. Now Dropbox interupt the saving process of an application (Planimate from InterDynamics). When the software saves it's file, I understand it does this to a temp file with ending .$$$. When the save process is done, and the file is verified, it replaces the orginal file with the new one and change the file ending the the appropriate. This has worked fine with Dropbox for many years. But lately Dropbox interrupt this and "lock" the temp file, making the software fail to save its files. Not very nice. I have to turn off Dropbox every time I do development nowadays. Please revert to a sync method less intrusive.
