I am having the same problems as described by CatchColt above. I have also wondered which is the latest or best the SeleniumWrapper or SeleniumBasic and what is the difference (if any)
I also get a run-time error 6 (Overflow) when I use Microsoft Edge with webdriver. What can I do to stop these errors occurring?
Thank you fir reading this.

I have noticed the same problem as CatchColt and NoviceDJ.
I am using Firefox 46 version. Any clues??

FYI, there is also an alternative to Selenium VBA, for those that might have issues with it: http://htejera.users.sourceforge.net/vbswebdriver/
