Background changes to white after pressing F5 to refresh (using 'STARTPAGE') an HTM file, solved by using MHT file (website) instead

Troubleshooting


Problem

Customer has implemented the background customisation technique, using the parameters 'ENABLESTARTPAGE' and 'startpageurl'.
  • TIP: For more details, see separate IBM Technote #374611.
However, when the user clicks F5 the background disappears.

Symptom

In one real-life example:
  • Immediately after launching Controller client, the background/website works perfectly (displays OK for the users)
  • The only problem is that if the user clicks F5 then the background (website) turns white/blank.
