If you are fldigi Mac user, take a look at your Logbook to see if the calls fit the "Call" box. I worked ZA/OK1DX this AM and the long call was too long for the box. This cosmetic issue is because fldigi has to use the OS X default system font, Arial, as the default font for the Mac version of fldigi. The fix to make a long call sign fit the call sign box is to go to fldigi's Configure/Colors & Fonts/Log and change the default Arial font to the Mac Menlo Regular font. I used size 14 but you may want something smaller. Any fixed-width font will work.
FYI, I use the Mac fixed-width Menlo Italic 19 font in my Rx panel and Menlo Regulal in the Tx panel. Don't forget to save the configuration once you have the font selections set to your preference.
