I didn't notice such problem. Which version of JDK are you using? I'm using JDK1.3.1 on both Windows NT and Solaris. It's easy to reproduce this problem on selection of very long messages or just dragging the mouse in the output window (push left mouse button and select/unselect text for some time and simulteneously look at the CPU load). Mikhail, how did you come to the conclusion that there is a performance problem? The CPU usage goes up when I select the text (by dragging the mouse) but then it goes down immediately. Does the CPU usage on your case stays at 100% level for a longer period of time? Are you sure that no other process is stealing the CPU? Hi Trung, I've faced this problem on a quite loaded sparc Solaris machine when I needed to select a huge piece of output. It turned out that it's almost impossible to do that because IDE requires 100% of CPU while selecting text in the Output window. I'm sure that it is IDE problem because absolutely the same thing happens on Linux and Windows as well. In all other applications that I've seen before, text selecting operation required insignificant usage of CPU. Resolved for 3.4.x or earlier, no new info since then -> verified. Resolved for 3.4.x or earlier, no new info since then -> closing. moving terminal emulator issues to terminalemulator component.
