1. Open a PNG file
2. F12 to open Paint.
3. Select pen in Paint.
There are now two colours available for pen - left click uses the "front" colour, right-click uses the "back" colour.
4. R-click to use "back" colour and make an edit by drawing a line
5. Save.

Expected result: Edit will be saved
Actual result: Edit is not saved.

Repeat Steps 1, 2 and 3
4. L-click to use "front" colour and make an edit by drawing a line
5. Save

Edit is saved as expected.

Just tried with a PNG with transparency:
Right click colour: orange, left click colour: green.
When I draw an orange line and a green line and then close Paint, the orange line disappears.
If I do the same with a PNG without transparency, both lines remain.
So it seems that the effect is caused by the transparency.
Please ask Irfan if this is a bug and tell us what he answers.

So it seems that the effect is caused by the transparency.

Not for me. I am editing a normal PNG file without transparency.

1 Start IV
2 Image > New
3 Save as >>> fred.png
4 F12 to start Paint
5 r-click to choose red (other colour was white) and make edit
6 Save.

The edit is not saved.

7 Open fred.png
8 F12 to start Paint
9 r-click to choose red (other colour was white) and make edit
10 l-click to make edit with white
11 Save.

The file is correctly saved - ie using l-click after r-click seems to "lock in" the original r-click edit.
