Hearts, spades and diamonds are recognized just fine. Clubs are miss-ID'd as spades. I've de-installed Java and removed the bin and lib folders, then reinstalled Java and downloaded a fresh copy of the solitaire-player .zip file. Program had been working fine until a few weeks ago. Windows 10 operating system w/32GBytes sdram, an Intel Core i7 5930K CPU, and an NVIDIA GeForce GTX 970 graphics card. No abnormal behavior to report elsewhere in the system.

Any suggestions will be most welcome! Thanks...
