I&#039;m using the excellent validator controls and for the most part they are working nicely. But every once in a while I get the following message :<BR><BR>"Unable to find script library &#039;/aspnet_client/system_Web/1_0_3705_0/WebUIValidation.js&#039;. Try placing this file manually, or reinstall by running &#039;aspnet_regiis -c&#039;."<BR><BR>I go ahead and run "aspnet_regiis -c" and things work again, but then the problem comes back. I&#039;ve checked the above mentioned directory to see if the file exists before I run aspnet_regiis, and oddly enough the file is there (so why am I getting the message?). Anyone else experience this? What&#039;s the long term solution?
