Need help with Windows flickers

[Alexis C]

I'am trying to create a solution where users can choose their prefered theme. It works fine, but under Windows XP, whenever I click a line in a list view (which have a button in the background)all images from the theme file disappear for as long as I hold the mouse button. I attached the files so you can see for yourselves (they are not from my original solution by the way, but a reproduction of what I'am doing). Is there a workaround for that or am I stuck with it?

Thanks in advance!

Hi Alexis - welcome to the forum.

I believe your flickering is not related to running a script but to moving through records.

The header updates to display information from whatever record you are viewing. When you activate a 'whole row' button, the record selection occurs before the script triggers, causing the (title) headers/footers to update.

Changing the layout to display Products through a portal on a User layout fixes the problem.

Also in the attached example, I changed the theme display from a relationship to a calculation trigger. I did this as a remedy, before I realized what was causing the flickering. I don't know which method is more efficient, but I suspect that my revision is an improvement.

Perhaps one of our resident gurus can weigh in on the subject.

shalom,

Matthew

Thanks! However this still leaves the theme selection drop down list (along with anything else I'd put there from the USER table) flickering... Definately an improvement though :

In my experience, if you are using Filemaker 9 on Windows XP and you have tried all of the optimization techniques and still have that unprofessional "flickering", "screen flash" or "slow redraw" problem then you may want to downgrade to Filemaker 8. This often results in an immediate improvement and in many cases completely eliminates the abnormalities.

For what it's worth,
