Status: RESOLVED WORKSFORME

There are alignment circumstances under which a flash movie assumes incorrect mouse positions, i.e. the actual mouse position is different from what the flash "thinks" it is. This prevents proper use of flash buttons or any other functionality that requires mouse positioning.

The following conditions will cause this flash mouse positioning bug:
- the WMODE of the flash is other than the default of "windowed"
- the positioning of the flash is such that its top edge is higher (or same height) than that of the page, i.e. "top" is <= 0.

When repositioning the flash dynamically with javascript the problem goes away, i.e. this may be repaint related.

I wonder if the underlying cause for this bug is the same as for bug 266933 (https://bugzilla.mozilla.org/show_bug.cgi?id=266933). That bug, by the way, is reported as FIXED, but in fact it is not fixed.

Reproducible: Always

Steps to Reproduce:
1. See test case




This bug has been around for a long time, I think pre 1.0.

I've tried the testcase with my debug build which has the fix for bug 271442.
It seems fixed with that.

This is worksforme with current branch (1.8.1) and trunk build.
