I have just downloaded 4.5
ouple of issues
1) The properties dialog for hyperlinks does not show from the context menu on existing links - it doesn't work on your demo site either
2) The class dropdown does not show the font decoration for each style. I'm sure this worked prior to version 4.0.0.7
For example my MainFontBold class shows as MainFontBold and it should look like MainFontBold
MainFontStrong should show as MainFontStrong and it actually shows as MainFontStrong
3) When I apply a class to a hyperlink the link no longer shows a different colour when it has been visited.
