>Let me know how stunning this form becomes <s>.

Changed things a bit, and now they informe a range of dates and I populate the grid with it. It's a lot better, and fast.
Don't shout at me, but this grid is suposed to be used as a Data Entry form ...
(OK, go mad, I wait for you to calm down ...)

The thing is, this is done in the Fox26 application in a BROWSE, they are used to it. There are 2 or 3 BROWSES working this way, all the other data entry is done in proper forms. Should I try changing this at this time ? Have you gone through this before ? Any strong argument a user would understand ? (besides that I would cry if they don't trust me anymore ?)
