This is shown as downloadable for QXP 10 Windows in the Extensions section of the Quark site (QXP10 logo against it). It looks though to be the same version that was originally for QXP 9 (iDropper 9 dated 2011) but when I put it in the Xtensions folder, QXP 10 doesn't recognise/load it.
I was interested to see if it now worked correctly as I have it running in QXP 9.5.4 but it tends to crash and lock up/freeze QXP if you move the mouse around too much looking for your new colour and always has done for me.
Is this the correct version for QXP 10(.0.2)?
TIA
