# DOS pauses in stdout/execution

I've been having this odd issue recently where my command line screens will basically lock the programs writing to them until I give mouse focus to the DOS window and then perform some keyboard action.

So, for example: I'll start a Tomcat instance and at some point, it simply stops updating -- I hit reload and nothing happens, nothing outputs to the Catalina window. Or, I'll check out something from SVN and it will appear to lag, but as soon as I interact with it, the lag stops.

## Edit

My aplogies, I used the word "screen" when I meant "window" (that is fixed).

The command (to start Tomcat):

C:\liferay\binaries\liferay-portal-5.2.3\tomcat-5.5.27\bin>startup.bat


The command to checkout a repository (in Cygwin):

\$ svn checkout <repository>


To the requests to change the operating system, I say "no". At no point have I mentioned which operating system I was using, I simply stated that I was using DOS (common use implies MS, but the comments stated that I have incorrectly stated which OS I was using). Since this problem has never exhibited itself in anything other than that environment, it is not intuitive to say that this is a Windows problem.

"Focus on the screen": This isn't DOS. What operating system is it? –  JdeBP Jun 15 '11 at 18:58
You are not running Tomcat under DOS. Edit your question to state your real operating system and real software including versions for your terminal emulator and shell. –  CarlF Jun 15 '11 at 19:02
Do you start this program from the command line, shortcut, or some other way? If from the command line or shortcut, please post this info. –  jftuga Jun 15 '11 at 19:02
