we reopened our TSY-557 issue for this and actually it should be quickly fixed. It should be in the next beta in about two or three weeks, so please watch our beta release notes for Resolved issues (2499928-1/TSY-557).
i’m using Toad 2.1.0.2921 with “Adaptive Server Enterprise/15.7.0/EBF 20037 SMP ESD#01 ONE-OFF/P/RS6000/AIX 6.1/ase157esd1rat/2923/64-bit/FBO/Sun May 13 00:04:36 2012”, and every time i open the conection get that error. Allthough i can succesfully connect and run queryes, i can not use the object browser.
this issue (TSY-557) has been fixed. Toad was throwing exception when there was “ON-OFF” text in the version string. Please, watch out for our next Beta to check whether your issue has gone.
Don’t know if this has also been fixed, but I just discovered that Toad also throws an System.FormatException when I open an sql file. And sometimes when you right-click on the sql pane.
