I know BlueGUI is discontinued, but it's not being caused by the plugin, it's from DBPro. Any time a web browser gadget is created, it won't show up at all. I noticed this, so I checked out the example program that I'd compiled back in 2009, and it ran with no problems. I re-compiled (with v7.7) it and it didn't run, therefore I'm pretty sure it had something to do with the DBPro version, not my computer or BlueGUI itself.
EDIT:
After extracting the old version of BlueGUI, I found out the problem was caused by the unofficial upgrade to BlueGUI that added support for the password fields. Delete this post if neccesary, thanks.
