[mythtv] [patch] osdlistbtntype m_itemList pos corruption.

[Kenneth Aafløy]

Hi!

I got a mail from Oscar Carlson today, claiming that I'd made the OSD menu 
behave badly with the wrap patch which got into CVS a couple of days ago. I 
did some testing myself, and discovered that holding down up or down button 
while in the OSD menu will cause corruption of the m_itemList's current 
position. This could be solved by either making a copy of the list in :Draw, 
or locking updates. I've attached a patch with the locking approach, but the 
copy of the list might be better. What do you think?

Oscar, does this solve your problem, or where you experiencing something else?

Kenneth
