LC 9.6.6 oddities when showing/hiding text

[prothero at earthlearningsolutions.org]

Jacqueline:
This appears to do the trick. I had other problems too, like locking the screen before I went to the card that was to display the text. But what you describe works and now I’m cleaning up the stack.

Thanks,
Bill

>>> Tnx, the reason I did the “do” stuff is because I wanted to programmatically vary the speed of the dissolve, initially, but it’s probably not necessary because most of the dissolves are the same. I have a pretty large app and I suspect there is some kind of timing problem because putting in a delay solved some of it. For me, the text fades in, then the field content disappears and leaves a white space where the field was. The background of the field is set to transparent, but I haven’t yet explored setting different options. I will do that today.
