Adam,
A problem was previously reported in these forums regarding the automatic duplication of meta tags within the code of a page being edited within a cutesoft editor.
I have identified through extensive user testing that this problem is definitely being caused 100% by the use of the Page Properties dialogue window, and is not being caused by having Skype running in the background on the users PC as was previously stated.
I hope this info helps you guys to identify and fix this irritating fault.
Other than that one issue, the editor is great and we now use a version of it to design, develop and maintain hundreds of website pages with absolute ease.
David
