If you get a blank page when downloading attachments from gmail, here are some possible solutions..

From:  http://tmp.garyr.net/forum/viewtopic.php?t=7938
workaround 1:
open TMP options > Links > Prevent blank tabs when downloading files >
EDIT
and remove from the list the line /disp=attd&view=att/
workaround 2:
lock the tab

Ctrl-click or middle-Click on the Download link
