I got the same, after 5 sec crash on Win 7 x64 (same auto it vers.)

M23, I really thank you for your feeds. I know that it's a drastic solution but I made some adjustments and now I like as this way looks like for the advanced setup of my script (actually it's a multifunction program to work with PDF and excel files for automated creation of complex hyperlinked PDF collections of thousands of pages for Final Documentation, like manuals, engineering docs and quality docs). #include

M23, You know, I'm just a proud self-taught who try and re-try till reach the goal I'm used to search through google filtering by site just when i'm stuck... but this is an other story ... I was not so clear asking, sorry... I'm not looking for internal colors, I'm trying to color just the grey nut where tab labels are or should be placed on. There is some different way from placing a disabled label over the unused space?

Thanks M23, it's a nice and elegant solution I think to know the answer to my next question but I'll try to ask anyway. Since all the GUI's of my script have a colored background, is it possible to apply some kind of background color or graphic style to a TAB control? PS. Yes, I saw all your releases and used some of them as example and other as they are. Many thanks for this!!

Hi, I was looking for a way to hide one or more Tab/s from a TAB Control by checking a checkbox item.

It works, anyway, could be improved by some of you (surely with more code experience than me) or eventually it could be helpful to someone.
