To be sure we're discussing the same, I've made some pictures of the different cursors.
Trader 1. Hand with pointing finger
This cursor clicks at the top left, where the finger is pointing.
Trader 2. Cursor shaped like an 'I', with a little triangle in the top left corner
This cursor clicks at the top left, where the little triangle is placed. This is the intended behaviour. However, as this text box only contains one line of text, and both the triangle and the 'I' are placed within the text box, you're able to click with the 'I' as well to end up in the same line of text.
In-game message. Cursor shaped like an 'I', with a little triangle in the top left corner
(The cursor you would like to change.)
This is the same cursor as the cursor of Trader 2. This cursor clicks at the top left, where the little triangle is placed. This is the intended behaviour. Unlike the trader text box, the in-game message text box contains multiple lines of text. If you try to click with the 'I' here, you would end up one line above where you'd like to be, namely on the line of text where the little triangle is placed. In other words: it is intended that you should aim and click with the triangle, not with the 'I'. If we understand you correctly, your idea is to be able to click with the 'I', just like the cursor on the Elvenar Forum (discussed below).
Forum. Cursor shaped like an 'I'
(If we understand you correctly, this is the cursor you would like to have for the in-game messages, without the triangle at the top left.)
This cursor clicks with the 'I'. You have to place the 'I' in the line of text where you want to type.
As mentioned above, the current cursors work as intended. We think your idea is to change the in-game message cursor to the cursor we have on our forum. Could you confirm this? Or, if you still think it's a bug, could you clarify it with some pictures?
