Subject: [PATCH] Fix crash on startup: call OnLimitChanged after _chkScale is
 initialized

The manual OnLimitChanged(null, EventArgs.Empty) call in the constructor
was placed before _chkScale was created, causing a NullReferenceException
because the handler reads _chkScale.Checked. Moved the call to after both
_limitBar and _chkScale are created and wired.
