[BUGs] CXTPHexEdit

1) If you try to select the Hexcode by Mouse (Not by Keyboard) beginning from the bottom to the top, so you will not be able to select the first byte.

2) If you try to select the Hexcode by Mouse (Not by Keyboard) and you move the cursor outside the client area (maintaining the left mouse button clicked), so the caret will start blinking. (You will get the same behavior for Ascii text).

3) If the position of the caret is at the first byte on the Hexcode and you press the left arrow key from the Keyboard and you maintain pressing the key, so the caret will dance on the first byte going left-right. (You will get the same behavior for the last byte with the right arrow key).

Thank you for your understand.
