Thanks, I've been thinking on expanding position with center when dock is not in full width/height. You can try using a wrapper for your app, in 32se AmigaOSse/menuicons/Autorun look how i did it... ;) hope you get it working ;)
I am copying over QDock to all my other installations and in one of them (again a 3.2.1 one) drop on icon doesn't work. I did a clean installation of QDock in that one but still it doesn't. Any idea why that happens?
Also, when you choose the full length dock style (X), on reboot the position is not right and instead of re appearing on the full length on the bottom of the screen where I left it, it appears shifted to the right and the left side of the dock is almost in the middle of the screen and the right end of the dock is beyond the right edge of the screen. You need to click the asterisk and bring it back to place on every reboot
Update for the drop on icon issue I had in one of my installations. It was my fault cause parm.library and WBRun was missing.
