Every other time I click a tab the close button switches from left to right. I have tried combine mode and a lot of different settings and it keeps doing this.

in combine mode it does this

To recreate this problem all I have to do is make a few tabs and then click one of the previous tabs. Sometimes it works the first time as expected but then a second go around it does this.
Would appreciate any help. It was doing this before and after version 1.5.
