sorry for the stupid question coming up, but exactly how do i create the DPF_TABSONTOP registry key? I created a dword with that name and a value of 256, but doesn't work..also tried string, binary & key (under the Mainframe Settings key)
i'm sure i'm missing something here
DPF_TABSONTOP isn't a reg key, it's the number of bits you need to add to the binDualPaneFlags key.
binDualPaneFlags has a default value of 9; add 256 (DPF_TABSONTOP) to this and you'll get 265. So change the value of binDualPaneFlags from 9 to 265 and you'll get your tabs on top. (BTW, these are decimal, not hexadecimal values.)
(Don't forget to close x2 before you edit the reg!)
