I don't know if anyone else has had this and found out what it may be.
I have two laptops, both running Linux/FF 22.214.171.124
On one of these, when a menu is displayed (for example the default context menu on the grid) the icons appear momentarily (usually only the first time the menu is displayed) and then disappear, with the menu text then being displayed to the left hand side within the border where the icons would normally be.
I cannot seem to work out why this happens or indeed what how it can be fixed. It may just be down to the installation on this one laptop but I am really curious to know anyone else experienced it and fixed it.
thanks for that. It is only happening on one machine which is bizarre. The fact that for a split second see the icons but they disappear is a bit of a mystery and to an extent rules out both of the recommendations below. One is OpenSuse 10.0(working) and the other SLED10.1(not working), though apparently it works under IE on this same machine. I can't understand what causes this.
