Hi list, First I want to point out that I've read the archives and am aware of Scott's advice to not use a repeat loop inside a mousedown handler, but to use mousemove / mouserelease instead.
However, I'm facing a problem for which using a repeat loop inside a mousedown seems to be the only solution, and of course I met the problem of the mouseup event not being trapped by my script. In a few words, when the mouse is down on an image (very large one, like a panoramic) the image is supposed to scroll back & forth horizontally according to the position of the mouse relative to the loc of that image, the scroll speed being proportional to the distance between the mouseloc and the loc of the image (actually like in a QTVR). So I used the following script : on mousedown repeat until the mouse is up show img 1 at max(-633,min(1432,(item 1 of loc of img 1)-(trunc(((item 1 of the mouseloc)-400)/10)))),300 end repeat end mousedown It works great (very smooth scrolling), except that the up position of the mouse isn't recognized about 15% of the time, and the img keeps scrolling even when the mouse btn has been released. It is obvious that I can't use mousemove, since the image must keep scrolling even when the mouse isn't moving, as long as it is down. I tried to use mousestilldown (which is a loop by itself) : on mousestilldown show img 1 at max(-633,min(1432,(item 1 of loc of img 1)-(trunc(((item 1 of the mouseloc)-400)/10)))),300 end mousestilldown It works (the release of the mouse btn is always detected), although the scrolling effect isn't smooth at all... If anyone has a brilliant idea for a possible solution, I thank him / her in advance...
