Notes: Flash 9 Gotchas/Bugs

This is also migrated over from labs. This was a list of bugs and gotchas I’ve run into over during my time as a Flash developer. I’m sure the best play to look would be Adobe’s Bug tracker but it doesn’t hurt to have a concise list of things to watch out for.

Bugs/ Gotches

• Bug

  wmode="opaque" or "transparent" disables KeyDown actions (not true in 9,0,60,0 beta) and disables MouseWheel actions

• Bug

  Textfields using pixel fonts and Static Textfield, render anti-aliased even if selected to render (no anti-alias).
  Fix – Switching to Dynamic textfield fixes issue.

• Bug

  wmode="opaque" or "transparent" text input fields do not allow special French (possibly other international) characters in Firefox

• Bug

  When calling getURL("someurl", "_self") (or anything besides "_blank", or null) from an event listener within a class, it fails.

• Bug

  If textfield is set to “anti-alias for readibility”, and textfield is scaled (by browser or otherwise). Text will scale smoothly, but letter spacing will jump . If the text is set to regular anti-alias, letter spacing jumping will not occur, and text will scale smoothly. If set to _sans, text will jump font sizes and not scale smoothly.

• Gotcha

  Exported items add file size if set to export on first frame

• Bug

  Setting a library item that has a textfield that uses a shared library font AND is embedding special character (or letters in general) to “Export for Actionscript” crashes the compiler.

• Bug

  JPGs wider than 2880px are cropped or simply not loaded.

• Bug

  Mouse.hide doesn’t work if the text of a dynamic textfields contains a link.

• Bug

  Unloading a swf from a level > 0 which has references to a runtime shared library doesn’t release it from memory.

• Gotcha

  mc.onLoad is only called if the script attached to mc is not empty.

• Bug

  Bitmaps below pixel 1639 are not shown correctly.

• Bug

  In Flash Players below 9.0.115.0, External Interface mangles complex structured data.
