On Windows Vista and later operating systems, you may not be able to use the keyboard shortcut [Ctrl-Shift-0] to set bookmark 0 (zero). This is because both operating systems pre-assign this keystroke shortcut to the Input Method Editor (IME). Microsoft documents this issue in a Knowledge Base article (http://support.microsoft.com/kb/967893).
Remove the shortcut assignment. To do this, follow these steps:
1.Click [Start], and then click [Control Panel].
2.Double-click [Regional and Language Options].
3.Click [Keyboards and Languages], and then click [Change keyboards].
4.Click [Advanced Key Settings], and select Between input languages.
5.Click [Change Key Sequence].
6.For Switch Keyboard Layout, select Not Assigned.
7.Click [OK] to close each dialog box.
This change does not require a system reboot to take effect. Once the change is made, the bookmark shortcut should work as expected in dcsTools Event Log Viewer.
