Has anyone else seen the following behavior in Maple 16 and/or 17? In worksheet mode, with 2-D math notation, after hitting <enter> to execute a line several times, the software switches, without warning and unrepeatably, to a mode where only the arrows work -and that is to scroll the sheet. This means the <enter> command is no longer recognized.
My only solution has been to click on the line with the mouse, for which it returns to input mode. This behavior started in version 16 and I switched back to 15. However, I prefer features of 17 such as the different subscript options, that I would like to stay in 17.
I note this behavior occurs on both my Windows based machines and have seen it on students' Mac based machines. We use a common site licence at our institution and I wonder if that might be the problem.
In short - it is a pain.
(Yes, I did try to look for other posters with a similar problem, but failed. )
