Dear list, I use SciViews R Console 0.8.9 with R-2.2.1 under Windows XP SP2, and it works very well for most of time. However, sometimes, when commands were executed by clicking F5, the error "Run-time error 521, Can't open clipboard" pop out. After choosing "Yes", the both R console and SciViews exits, and all things in the Command window losts, which is very annoying. Could anyone tell me how to avoid this problem? Thanks. Wuming
