Sorry, You did not understand my question. I try to be clearer.
On the demonstration site you have configured an example where you have 3 buttons in the first column of each row, E, S, C. I replaced those buttons with images. What I found is that tool tips (titles) does not work.
No, I don't think. The img line works just fine outside the grid. Something is preventing the Title from displaying inside a cell in the grid. I think that might be the case for the button as well, at least in Firefox.
I do specify both Alt and Title.
I will be away for several days on holiday. Hope you enjoy yours!
I will be back at it on Dec 26th.
By the way, the forum is working better now. Occassionally I have problems with line wrap, but no big problem.
