This morning for no apparent reason, when trying to open a Word document I get the following message: The command cannot be performed because a dialog box is open.Click OK and then close open dialog boxes to continue. Clicking OK reveals a Microsoft dialog box stating that Word experienced a problem trying to open a file. By clicking OK on that dialog box, the Word document opens. I have Googled this issue and have not found any answers that make any sense, and I have done nothing to my knowledge to create this problem. Yesterday it worked fine, this morning it does not. Would appreciate hearing from anyone who has had this problem or knows the fix. vs PS: Do not have Norton Antivirus, and nothing has been changed with Adobe since yesterday.
