Hi Valentijn,
I'm glad to hear that you'll be out here next week. Why don't we plan on
spending some time discussing your needs about time selection while you're here?
Also - the bug you mention below should be fixed now.

> 3) the -possible- bug:
> It seems than since you revamped the chooser, selecting images using the
> "SHIFT/"CTRL" buttons seem to work still o.k., but if i select times not
> connected to each other ("CTRL") the times in the current view of the listbox
> jump back to the first position of my previously selected subset. So then i
> have to scoll down to the "time" is selected last (that was, with my "CTRL" +
> left-mouse) to continue the filtering process.

> Btw. I'll be seeing you soon as Willem van Nieuwenhuis (our programmer which
> joined our department recently) and i will attend the upcoming "Advanced IDV"
> and "JAVA netCDF IO" workshops....
