In the wxt terminal under winXP/win7, the plot is not raised (by (re)plotting or via "raise") if it´s window was minimized to the tray before. It does get raised in both cases if it was only hidden behind another window. Only wxt is affected, the windows terminal works fine.
This shows on gp465rc2 and gp50alpha, binaries from sf.net. Same with old gp444 and 463. I can´t remember when this first showed up, but it´s definitely not that old. Probably some interaction between wxt and a recent windows update?
