It also very annoyingly pauses the whole system, so that even typing becomes slow. Also, I'm sometimes (rarely) getting messages like these: osl-0898 [37] os_wait_semaphore : Failed to acquire semaphore[c12ce560|1|0], AE_TIME osl-0898 [41] os_wait_semaphore : Failed to acquire semaphore[c12ce560|1|0], AE_TIME This is using 2.4.22 on a Sharp Mebius PC-MT1-H5. --J. ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
