Harold's ArrowKey Handler problem (please enter a subject)

[Haroldo Mauro Jr.]

Hi Mark, thanks for adding a subject to the thread. Sorry I forgot to do it.
No, I don't there is no other arrowKey handler anywhere. I did a search just to make sure. The script IS a stack script. The navigationArrows property is set to true. The short script is an example from the dictionary. The long one is mine. I'll try the suggestions I got from the listers. Thanks again.
Harold

Probably it would be still easier to move the script to stack level. You will also need to set the navigationArrows to true. I tried your short script and it works fine for me this way. Your long script should work fine, too (perhaps with some minor modifications).

Instead, use files, MySQL, SQlite, custom properties or one or more fields as containers. Use the card solely as your interface and not as a data holder. This is makes your stack often faster and you will be able to detach data from the standalone, which may be necessary. Naturally, if you have imported a HyperCard stack, this advice probably won't help you much until you start making brand new stacks with RunRev.

>>Hi everybody, I just joined this list. I used Hypercard for many years, since I got my first Mac in 1991. Then, some years ago swiched to  Supercard, which I've been using a lot.  I've had Revolution Studio for over a year but only now am trying to use it more steadly. So, here's what I need help with right now.
>>In a converted Hypercard stack, an arrowKey handler in the stack script is not behaving as expected. So I checked the Revolution dictionary and found this example below, which I tested on my stack and it didn't work, just the same:
