Hi folks.
I've tried everythig to fill any forms (squares, polygons, etc.) but with no success.
In the lower part of the desktop I've found the color toolbok, selected "yellow" but nothing happens. The properties window confirms it's the same color picked.
Please see picture attached.
Am I doing somethig wrong or shoul I reinstall the program?
Thanks for this lovely (and free) software.

Hello,
It seems very simple
Check your left panel at the "A:" color bar. It's in zero "0". It means it's totally transparent. So just move the control all to the left.
Hope I have been understood

Also note that not just the A slider is at 0 but the opacity/opacidad is at 1,1% instead of 100%.

The rectangle tool is preserving the last used style by default so you need to change the alpha value and the opacity to fully opaque before you see a visible effect of picking the colours from the bottom palette and/or when drawing a new rectangle/circle/etc.

Thank you both hulf2012 and Lazur URH.
I'd made both adjustments and now it's OK.

I guess I'm a bit late to this thread, but I wrote a tutorial to help find where this kind of problem is coming from. http://forum.inkscapecommunity.com/inde ... article=18
