Weird VO behavior

Subject: Weird VO behavior

Dear AXDevelopers,

I have encountered a strange VoiceOver behavior where I need TWO shift +ctrl+opt+down arrow keypresses in order to interact with an item I have inside another item. I have accessorized a completely custom table (XYZTable) as a user pane which embeds possibly many XYZTableItems. Each XYZTableItem is also a user pane with embedding features and embeds a single AXMenuButton or nothing. Mac OS 10.4.8, PowerPC.

The problem: I can navigate to each XYZTableItem normally. The problem appears when I want to interact with the table item as I have to use two shift+ctrl+opt+down arrows. Then I get to the AXMenuButton. Now when I press ctrl+opt+down, the VO cursor moves onto the next table item so it encloses the entire XYZTableItem as expected. When I return back via ctrl+opt+up, the cursor moves back to the AXMenuButton rather than the entire XYZTableItem.

Questions:

1. Anyone knows why do I need 2 interactions to get to the menu button? I have never encountered such behavior. 2. What a strange behavior there is with the next/back?

Thanks,

  Tomas Zahradnicky
