Ridiculous

I have used PDF Reader X for several years with great satisfaction. This has however dramatically changed recently - I absolutely see no point in reminding PDF Reader X users every 10 minutes or so through a very annnoying popup window and a bouncing dock icon to upgrade to the Pro version.
If anything, this has prompted me to uninstall PDF Reader X and install an alternative PDF reader from a company that has higher standards for professional courtesy towards its customers.
