Hello Rini Boo,
Please, accept my apologies, I forgot to send you the fix. Here it comes:
1. Create a new CSS file (for example Fix.css) in yor project, and paste the following CSS in it:
padding-left: 4px !important;
2. Set DialogsCssFile="Fix.css" to the server declaration of RadSpell, and make sure you specify the corect file path. This will load the fix file in the window of RadSpell.
3. Reload the page
