A few of us started having this problem a few weeks ago. It comes and goes, but is present more than it is not. SQL Navigator Professional Edition 22.214.171.1240.
There is usually a lag between pressing a keyboard key and when the key appears on the screen. You can type an entire query and nothing appears on the screen until 2-5 seconds after you stop typing. The more you type, the longer the lag.
We haven’t been able to figure out what triggers the behavior. Sometimes SQL Navigator will show the behavior as soon as it starts, other times it suddenly starts. We use SQL Navigator for an Oracle 10 database and an Oracle 11 database and we have the problem with both databases.
Restarting SQL Navigator does not solve the problem. Reinstalling SQL Navigator likewise doesn’t help. Upgrading is not going to happen any time soon. Any ideas?
