Warning - Could not delete the file

Hi all,

If I accidentally leave Dropbox on (synching) and I render into a Dropbox folder, when the render is done I get an infinite list of alerts from After Effects, saying that it could not delete a bunch of AEtemp files. 
Can we have just one alert instead of one alert per file? 

Currently I have to stick my finger on the Esc button for several seconds and wait to see how a trillion alerts come and go one by one. Annoying like a sermon.

Cheers
