Cant resize ImGui menu in game

[TrilloxR]

So I was recently making a multihack for CSGO but I run into a really weird problem. I can't click my ImGui menu, and it looks not really good.

For anyone wondering I m using the DirectX 9 Keiro Hook 2 base

Some people say that windproc is causing that problem, but I don't know.

Try using ImGui::SetWindowSize(ImVec2(A,B));
A = your x size
B = your y size
I hope this could lead you too your solution.
