You need to explain what your structure here is in more detail. 1. is the WebBrowser in a Container Control (like a Panel) ? 2. what exactly makes you unable to see your form ? what's covering it up, or on top of it ? 3. where is the Button that triggers the use of ShowDialog ? 4. what is the purpose of the Dialog show ? 5. how is the TaskBar involved here ? 6. what is the "Windows profile" you say you have to remove ?
When I consider the brief span of my life, swallowed up in the eternity before and after, the little space which I fill, and even can see, engulfed in the infinite immensity of spaces of which I am ignorant, and which knows me not, I am frightened, and am astonished at being here rather than there; for there is no reason why here rather than there, now rather than then.
Blaise Pascal
