After a period of inactivity (e.g., several minutes), the user may click on a button to run a script (e.g., change layout or sort the columns) and Webdirect sometimes loses graphics. All of the text is displayed and properly aligned, however, the theme (Basic-Classic), button graphics, sometimes text box borders, etc. are missing. Subsequent clicks on buttons (e.g., sorting, find) does not restore the theme or styles.
Note that this "text only view" can be seen sometimes when the page loads normally but it usually quickly switches to the "theme view" in the WebDirect interface.
In the image below, the top panel shows the text only theme and the bottom panel shows the correct theme and colors.
How to replicate
We could not replicate exactly yet but the issue may be related to a period of inactivity on the loaded page.
