GUI issues in web applications are altogether different from LAN based applications. Some of them are:
- supporting of frames in different web clients
- enabling and disabling features
- displaying of images in different versions
- Showing of web page contents properly in differnt resolutions.
- Keyboard support (ENTER, tab etc.)
- Different setting of browsers should not hamper working of web application.
- Correct messages (same as in LAN applications)
- Resizing of windows in Netscape/child windows.
