Probably a very stupid question.

After hesitating for a very long time I decided as a very satisfied user of MAPLE 12 (Classic worksheet, I'm very conservative) to migrate to MAPLE 14.
However the processing of the files is very slow, autosaving takes for example about 2 minutes while with MAPLE 12 only a few seconds. Saving the file gives an alert: there can be problems in saving due to formatting problems.

I think I have to do some formatting of my MAPLE...

For my technical applications I use the incomplete EllipticE(z,k) = int(sqrt(1-k^2*t^2)/sqrt(1-t^2),t=0..z) and Incomplete Elliptic integral of the first kind EllipticF(z,k), both with z positive but arbitrary and with 0<>
