In my web-application, I have a simple web-page that pops-up and allows the user to upload a file. A problem seems to arise when a user enters the screen for the first time and attempts to upload a file greater than 1mb, the button click event does not fire. If the user closes the the pop-up and then attempts the process again the upload works just fine. Also if the user uploads a file less than 1mb the upload will work fine on the first try. Not sure what the issue is here.
Any help would be appreciated.
