Has anyone ever encountered error 50290 ("Application\ndefined or object defined error") when trying to write to\na worksheet containing a 3rd party ActiveX Control?\n(i.e., The line 'Worksheets("Sheet1").Range("A1").Value =\n1' causes an error.) This error seems to occur\nocassionally and spontaneously. I have tried everything,\nbut I know I'm not alone. (Search Google for Excel Error\n50290 and you'll find several hits - but no solutions.)\nThanks in advance.
