Has anyone run across a problem where using the 'post' method to submit a form works 99% of the time but occasionally results in blank values being submitted to the processing page? We know the form fields were completed because of the client side validation (the server side validation returns an error message stating that all of the fields were blank). This seems to happen if the browser (so far only in IE 5.x) is open for a long time but if you open a new browser and retry the problem does not exist. We are using IIS 4 and we are not using sessions. Converting the 'post' to 'get' for the method also seems to correct the problem (we would like to use 'method=post' due to the limited length of the querystring/get method).
