Something strange is happening with my Lightroom (I must admit that it did not begin suddenly but as soon as I installed the software on my Imac):
Suppose I write a number on the exposure slide, when I hit Enter (or tab, or any key) the slider jumps back to 0.
There is no way that I tried to change the values there and it jumps back again to 0.
The only way to change the values there is move/drag the slider with the mouse or use the up and down arrows (to increase the exposure and down to decrease).
How do I fix this problem?
