In a previous article I wrote regarding my pleasant surprise of the ease of use and power of Corel WordPerfect X3.  I stand behind the article and still claim that it is the best office product I have used.  But one issue with its use did put a kink in my workflow.  As an early adopter of Microsoft Office 2007 many of my files are in the new.docx format.  Corel WordPerfect X3 could not open the new Microsoft format.  The work around for me is obvious, I simply Open it in Word and save it back to the old  format.  But if I used Corel WordPerfect exclusively it could present problems if clients sent documents in the new format.  I contacted Corel regarding this issue, and they too expressed concern about this issue.    Corel made the following statement regarding support: “Corel would move to make “Open, view and edit” capabilities (Saving will be to the binary formats at first) available in WordPerfect Office for both Microsoft Office OOXML and OASIS ODF in 2007″
Although they did not give me a date of when this would be supported they said it would be soon.  I will post information as soon as it is available.
If you are not sharing files on a regular basis with MS Office users this is not really an issue, but for those actively sharing documents with office users this is an area of consideration.  My personal recommendation would be to keep using what you are now until the support is available.  If you must make a purchase now, I would still recommend Corel Word Perfect X3 because the time and effort you will save by using a better product will be well worth a few headaches until the new format is supported.
