   The problem is that when loading another PNG (most likely gif as well) the color reduction slider is fixed onto value field not the % of current slider position.

   If we set slider to 100% and load 13 color image it will put in the field 13, slider is still on 100%. Then we load image with 40 colors, but the field stays on 13 and slider is rescaled, so we end up with color reduction even if we had previously slider on 100%.

   User fix: none, suggestion: RIOT should re-read value from slider not from the field. (or make it as a setting to decide for user)

   If doesn't seem to be related to 2/4/16/256 color depths.

   This is very nasty when we use maximum compression, because we have to wait for a recompression twice. First after the load, then after we correct the slider to 100%.

   Are you sure this happens in the auto mode? Sounds like something happening inthe manual mode... In manual mode I can't touch your settings even if they were left as is from previous sessions. I can only disable or fix what's not exportable.

   Och, I forgot to mention - yes it is related to manual mode. Loading another image keeps the int value not % of the slider. This way it cuts off the colors even if we had previously the slider on 100% just because the second image has more colors than previous one. Of course we are talking about indexed pngs, not true color.

   This is normal behavior for the manual modem Just use the automatic mode if you need it to work like this. Then you can always change any setting going in the manual mode again automatically
