Bug in tabs?


Hi,
I'm creating a tabs widget where I provide a "selected" option with an
integer. The proper tab is selected from the beginning, but the first
tab clicked after that is selected without the originally selected one
being deselected.
That means that after the first click on (another) tab, two tabs are
selected (graphically) at once.
Later clicks work like they should.
Is this a known issue (I'm using 1.7.2)? Any good workarounds?
Thanks,
