rxvt terminal crashes in SuSE 9.1

I much prefer rxvt over xterm. But there is a glitch with SuSE 9.1, and AMD Opteron chips. If I right-click, once or twice, on the window, rxvt closes with the error rxvt: XError: Request: 18 . 0, Error: 2 Such right clicks are often finger errors. Also, I cannot highlight text for cut and paste without a crash. This is extremely frustrating. This problem does not occur on standard 32-bit chips. I also don't remember it happening on SuSE 9.0 (with the 2.4.21 kernel). Please help. Thanks.
