Edward has introduced Excaliber 4.2, which not only cleared up my Vegas 6 toolbar icon issues (see previous posts here), but features some nice upgrades as well.
I really appreciate Edward's responsiveness with this stuff. Excalibur has become an indispensable tool for what I do and Edward's continued support is making my Vegas experience better and faster all the time!

Does this include the "disappearing toolbar icon" issue?
This is extremely frustrating when you have to shutdown Vegas and restart just to get the toolbar icons to reappear. This issue has existed since Vegas 5, and I think even 4, but I'm not sure about 4. 5 & 6 definitely has this bug.
It has definitely worked for me. You will now have an Excaliber 4 icon for both the .dll and the .js file, both of which activate E4. Been using for repeatedly now with no problems at my end.
My problem had been that my png icon would revert to a non-functioning .dll file repeatedly after I had modified the toolbar with the .js icon. Not sure if this is what you mean by "disappearing."
If you mean ALL the icons disappearing, that is a Vegas issue. (i.e. you hover over where the icons *should* be and the proper info shows but there is no image). I've seen this happen and simply going to Tools - Scripting - Rescan Script Menu brought them back.
