Windows security login displayed in asp.net app hosting Aspose.words

HI,
Sometimes when I close the web form, that is hosting aspose.words, I get the windows securtiy login dialog. All I have to do is cancel the dialog and everything works fine.
Please note that my asp.net application is using an impersonated aspnet user. How can I avoid having the login security prompt.

Looks like security configuration issue. It is hard to give a qualified answer due to the lack of information.
Please provide the screenshot of the dialog. I will check what could be done. Any additional information you can provide will be helpful.

I am providing you with a screen shot of the login dialog that pops up when I exit the web form that instantiates aspose.words.
Regards,

I am afraid that we need to look at your source code to find the root of the problem. Please attach your source code if it is possible.
