thanks a bunch
I tried all three codes the extensions load up with no errors but it will only show two window class sidebar ext at a time. I have to disable one that shows up to get the third ext to show in its place, super weird. all the ext work fine in any combo with only one other ext loaded with any of the example codes. just two at a time. weird all none sidebar window class ext doesn't have this issue. I also tested all three ext with all three codes on CoreRpg same issue. I can record, and post a video of it if you want. I'm taking a long smoke break before I post the video! oh, I also tried to load ext I didn't create like the sidebar demo, the file you gave me the same thing happened.
