To follow up. This seems to be caused by an AHK script running at the background some users have installed which also is an addon for the game.

@Kyusung4698 thanks for the info.
From our aspect, it’s not a common issue, so we classified it as a low priority.
Having said that, our R&D is investigating, and we will keep you updated.

Thanks.

Another user without an AHK script. Can this get a higher priority?

@Kyusung4698 we’ll check if there’s a workaround/fix for this issue.
Can you please send us an example for such an AHK script that blocks the placeOnClipboard function?

@itayG I’ve created following plugin to fix this issue myself.

github.com

Kyusung4698/PoE-Overlay/blob/develop/plugins/src/clipboard/Clipboard.cs

using System;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace overwolf.plugins
{
  public sealed class clipboard
  {
    public void placeOnClipboard(string content, Action<object> callback)
    {
      startSTATask(() =>
      {
        try
        {
          if (!string.IsNullOrWhiteSpace(content))
          {
            var obj = new DataObject();
            obj.SetText(content);
            Clipboard.SetDataObject(obj, true);

@Kyusung4698 thanks for sharing! I forward your solution to our R&D, to check if they can use it or want to implement other solutions. Anyway, I’m glad that you find a workaround for now.

Thanks.

FYI: In version 0.155 overwolf.utils.placeOnClipboard and overwolf.utils.getFromClipboard reimplemented so that we tackle the coexistence issues with AutoHotKey.
