OK, there should be a couple approaches to getting a screen shot, but in modern laptops you may have to experiment -- what you want is a capture of just the active window. This was Alt-PrtScn in a "traditional" keyboard. But there is a catch in the keyboards with fn and that won't work. And, just pressing fn-PrtScn will copy your whole desktop into the clipboard.
OK, I got it started! Bring up the Convert and Save dialog with an image selected and enter the settings you would normally use. Then, with that dialog active, press fn-Alt-prtSc. Then, open MsPaint -- you will get a New image window. On the left side of the toolbar there will be a Paste button/tool which should look "active" meaning there is something in the toolbar. Click it and only the Convert and Save dialog will show up in Paint.
Then, you may want to resize it or not. But, for now, try to just Save As a jpeg, setting your quality to a level that will give you a small file size. If the file size comes out to within 150Kb, then the quick and easy way to post it is to use the POTN Attach method -- in the Reply window you click the Advanced button and then in the new toolbar you will see a little paper clip icon at the top with the Attach tool tip -- click it and then you can Browse to the screen shot jpeg and grab it, then you click upload and it will be in POTN. Then click again on the Attach tool and select the jpeg you just uploaded and it will appear in the Reply window surrounded by the Attach tags.
There! It sounds complicated at first try, but I could figure it out and I had never even opened MsPaint, and had not messed with this with the fn stuff either
