Summary: data.frame column recovery causes lots of pop up messages

Initial Comment:
Hi!

If you create a data.frame, browse it and remove a column using the command line while the data.frame is still opened as a tab, a message pops up asking whether you want to recover the deleted column. This is no problem if only one column has been deleted. However, if more than 20 columns have been removed -- which can happen easily -- the messages become really annoying and the only way to get around clicking through all of them is to to kill the rkward process.

Here is an example:

# create data.frame
x <- data.frame(a=1:2,b=2:3,c=1:2,d=4:5,e=6:7)

# browse the data.frame using the rkward gui and keep the tab open

# rewrite data.frame
x <- data.frame(a=1:2)

# messages pop up asking you whether you want to recover the deleted columns


It would be great if changes to an opened data.frame could be handeled using one dialog, e.g., like R script files that have been modified by an external program.

I'm using: rkward 0.5.7, KDE 4.4.5, Debian Squeeze, R 2.15.1.

Regards,
Birk
